Eclipse: start a new Java project with an existing package??

I have Java classes in (1) my choice of directory and (2) my choice of package.

How do I create a NEW Eclipse project that uses my exising Java classes with their packages?

(The Eclipse issue I'm facing: It keeps trying to move my files into a new nested directory named after my package... and I don't want anything to move. Or it wants to delete the package statement in my source code. Nope, I don't want that, either.)
